True Active/Active Metro Stretch Cluster

How’s this for raising the bar on enterprise storage: Purity ActiveCluster does away with decades of cost and complexity in business continuity and disaster recovery by delivering a true Active/Active cluster that’s simple and built-in.

ActiveCluster – Ultra-simple, ultra-Included

ESG: ActiveCluster is Transparent and Effortless

Market intelligence firm ESG put ActiveCluster through a battery of business continuity tests. They found that “Purity ActiveCluster takes the cost and complexity barriers out of business continuity, making it simple, cost-effective, and provable for any organisation—and relieving the minds of IT administrators.”

Synchronous Replication

Writes are synchronized between arrays and protected in NVRAM on both arrays before host acknowledgement.

Symmetric Active/Active

Read and write to the same volumes at either side of the mirror, with optional host-to-array site awareness.

Transparent Failover

Automatic non-disruptive failover between arrays and sites with automatic resync and recovery.

Nothing else required

No third site, no extra hardware, and no software licenses. Just a simple, non-disruptive Purity upgrade.

LONG DISTANCE PROTECTION AND DR IS BUILT-IN

Active-active asynchronous replication provides robust out of region disaster recovery protection with intelligent replication technology. Maintain your disaster recovery RPO even if one of your ActiveCluster arrays becomes offline regardless of which ActiveCluster site is online. The loss of either source array or a replication link is transparent to async replication.

Performance Optimised, Always Available

ActiveCluster uses a preferred array setting to ensure that hosts have the best possible performance. This ensures that writes from the host only use one round trip to be synchronously replicated between arrays, and that reads are always serviced by the local path.

ACTIVE/ACTIVE IS KEY TO ACTIVECLUSTER

Multi-site, Active/Active design for synchronous and asynchronous replication is fundamental to the effortless experience of Purity ActiveCluster. Unlike Active/Passive implementations, ActiveCluster serves I/O on the same volume from both sites simultaneously. You don’t have to worry about the complexity of managing VM or database instance affinity to a site, and application latency is optimised with reads served locally.

Designed to be Easy and Automatic

Managing an ActiveCluster stretch cluster is as simple as managing a single array: snapshot and clone operations can be performed from either array, and volumes and snapshots are synchronously maintained on both arrays. Failovers are transparent, and the arrays automatically resynchronize.

Get started with Just Four Steps

Stretch cluster deployments have typically been intimidating from the customer’s point of view. Look at the length in pages of the manuals from some of our major competitiors: 769 pages; 1,360 pages. It doesn’t have to be that way. You can launch ActiveCluster in minutes – with just four steps.

Management is Simple as SaaS

Nothing to install onsite or configure and support, no hardware or software to maintain, no security patch updates.

AutomaticThird Site

An integrated, cloud-based mediator is inherently a separate failure domain, and not subject to human error.

Automatic Configuration

Arrays configured for ActiveCluster will automatically connect to and use the Pure1 Cloud Mediator.

Mediation Can Be Passive

Continuous access to the mediator is not required for normal synchronous replication operations.

WHAT’S THE ACTIVECLUSTER FAILOVER PROCESS?

If array communication is broken, both arrays briefly pause I/O and query the mediator. The first array to reach the mediator keeps its synchronously replicated pods online. The second array must stop servicing I/O to its synchronously replicated volumes in order to prevent split brain. The entire operation occurs within standard host I/O timeouts to ensure that applications experience no more than a pause and resume I/O.
